The following example de nes two important relations associated with any function f : X !Y. WebSymmetric relation is defined In set theory as a binary relation R on X if and only if an element a is related to b, then b is also related to a for every a, b in X. Let us consider a mathematical example to understand the meaning of symmetric relations. Define a relation on the set of integers Z as 'a is related to b if and only if ab = ba'.

WebExample 1: A relation R is defined on the set of integers Z as aRb if and only if 2a + 5b is divisible by 7. Check if R is reflexive. Solution: For a ∈ Z, 2a + 5a = 7a which is clearly divisible by 7. ⇒ aRa. Since a is an arbitrary element of Z, therefore (a, a) ∈ R for all a ∈ Z Hence, R is a reflexive relation.
